Abstract
The utility model relates to a large disk combined blade saw which belongs to the field of the fabrication of combined blade saws for the baiting of rail switch products. The utility model comprises a cutter body, wherein the circle of the cutter body is in a convex-concave structure, and the convex part of the cutter body is provided with blades. The utility model has the advantages that the utility model better combines the strength and the toughness of the cutter body and the cutting performance such as the strength, the abrasion resistance, the heat resistance, etc. of a cutting part; the utility model solves the sawing and the baiting of sections of rail component materials such as PD3 type rail, etc. with high strength and high toughness; the utility model realizes the sawing and the baiting of rail component materials at high speeds, compared with the baiting of original sawing machines, the utility model increases the work efficiency by 200%; compared with the original sawing machines, the cost of tools is reduced by 70%; in the utility model, one blade has functions of four blades; the utility model has convenient adjustment, simple installation and flexible replacement, and reduces the labor intensity of operators.
Description
Technical field:
The utility model relates to a kind of large-scale disk combination butcher's saw, belongs to the blanking of railway switch product and saws the manufacturing field with composite blade.
Background technology:
Once used band saw, saw blade cutter, welded type carbide-tipped milling cutter etc. in the blanking operation of track switch product, all undesirable.The weak point of its existence: (1) band saw: not reproducible use, if the part monodentate of whole saw blade damages, a then whole bands for band is scrapped.(2) saw blade cutter: reusable, but need special-purpose trimming equipment and personnel, rehabilitation cost is higher.(3) welded type carbide-tipped milling cutter: band saw and metal saw saw technology intensity and toughness in order to look after cutter hub, select high speed steel material for use, but sacrificed simultaneously the specification requirement of the hardness, wearability, hear resistance etc. at cutting position cutting ability.The welded type carbide-tipped milling cutter has overcome the shortcoming of band saw and saw blade cutter, promptly taken into account the cutting ability such as hardness, wearability, hear resistance of intensity, toughness and the cutting tip of cutter hub, but crackle takes place or produces internal stress in welding in welded type carbide-tipped milling cutter often, thereby causes blade that crackle in use takes place.Simultaneously, it also exists monodentate to damage, and then whole milling cutter is scrapped or the problem of maintenance difficult.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, design the hardness of a kind of intensity that can either take into account cutter hub, toughness, cutting tip, and have the large-scale disk combination butcher's saw of cutting abilities such as wearability, hear resistance again.
Design: consider that this circular saw is mainly used to cut off rail, and be subjected to former lathe spatial constraints that cutter diameter adopts 710mm.Cutter hub requires to have sufficiently high intensity and toughness, considers the raising of production efficiency simultaneously, requires to have bigger cutting output.So novel large disk disc cutter overall structure is divided into cutter hub and blade two large divisions, cutter hub adopts indexable high strength and high tenacity 42CrMo Hardmetal materials,
Blade adopts carbide chip, and adopts machine card type mounting means (blade is stuck in the protuberance of cutter hub circumference), and is easy for installation, changes flexibly.This technological break-through the forbidden zone of large-diameter saw blade unit mahine card, solved large-diameter saw blade rigidity and machine card the combination contradiction.Its technical scheme: large-scale disk combination butcher's saw, it comprises cutter hub (1), the cutter hub circumference is convex-concave structure and at its protuberance blade (2) is housed.
The utility model is compared with background technology, and the one, this technology has been taken into account cutting abilities such as the hardness, wearability, hear resistance of intensity, toughness and the cutting tip of cutter hub well; The 2nd, solved the section sawing of high strength such as PD3 shaped steel rail, high tenacity rail spare material; The 3rd, realized the high speed sawing of rail spare material improving work efficiency about 200% than original sawing machine blanking; The 4th, tool expense reduces about 70% than original sawing machine; The 5th, because blade adopts carbide chip in this technology, and adopt machine card type mounting means, the rectangular structure Design of blade, realized the effect of a blade top four blade, promptly each angle of rectangular blade all is a cut point, damages one, adjust still unspoiled angle as long as rotate, can continue to use, have only under the situation about all damaging when four angles of rectangular blade, blade just need be changed, and it is easy to adjust, simple installation is changed flexibly, has reduced operator's labour intensity.
Description of drawings:
Fig. 1 is the main TV structure schematic diagram of large-scale disk combination butcher's saw.
Fig. 2 is that the structure intention is shown in the amplification of I among Fig. 1.
Fig. 3 is that the side of large-scale disk combination butcher's saw is cutd open structural representation.
Fig. 4 is the structure for amplifying schematic diagram of II among Fig. 3.
The specific embodiment:
Embodiment 1: with reference to accompanying drawing 1～4.Large-scale disk combination butcher's saw, it comprises that cutter hub 1 and cutter hub adopt prior art to make, and are not described herein at this.The cutter hub circumference is convex-concave structure (convex-concave structure continuously) and at its protuberance blade 2 is housed.Blade 2 adopts the machine card structures to be installed in the protuberance and the moving angle of adjustable turn over of cutter hub circumference), promptly blade 2 is connected the protuberance of cutter hub circumference by screw 3, blade 2 rectangular (square, rectangle etc.) and adopt carbide alloy to make.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations are just illustrative to the utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
